Throwing ArgumentNullException

Question

Suppose I have a method that takes an object of some kind as an argument. Now say that if this method is passed a null argument, it\'s a fatal error and an exception shoul

Answer 1

I prefer the explicit exception, for these reasons:

• If the method has more than one SomeClass argument it gives you the opportunity to say which one it is (everything else is available in the call stack).
• What if you do something that may have a side effect before referencing x?
